One of the Worlds favourite pens for over 20 years, the uni-ball Eye Micro rollerball delivers a smooth, clear and exact writing experience. Like many of uni-balls products it combines their unique uni-flow consistent ink delivery with uni Super Ink technology which means it is water, fade and tamper proof. The window barrel allows you to see when the ink is running out and combined with its extreme reliability this means there are no concerns about the pen suddenly stopping or running out unexpectedly. Because of the micro-detailed nature of the lines the Eye Micro produces it is perfect for fine writing and also for sketching and technical drawing. PensGBP013178
